About This Estate Tax Calculator

The Estate Tax Calculator helps you estimate federal estate tax liability based on current IRS exemption amounts and progressive tax rates.

5. Click Calculate — Press the "Calculate Estate Tax" button to see your estimated federal estate tax due.

How It Works & Formula

The federal estate tax is calculated on the taxable estate, which is the net value of all assets minus allowable deductions, plus any lifetime taxable gifts. Only the amount exceeding the annual exemption is taxed at a marginal rate (currently 40%).

Estate Tax = max(0, (Gross Estate − Deductions + Lifetime Gifts − Exemption)) × Tax Rate

Where:
Gross Estate = Total value of all assets owned at death.
Deductions = Debts, funeral expenses, administrative costs, charitable bequests, and state estate taxes.
Lifetime Gifts = Cumulative taxable gifts above annual exclusions.
Exemption = Unified credit exemption amount for the tax year (e.g., $15,000,000 for 2026).
Tax Rate = Top marginal estate tax rate (40% under current law).

📐 Mathematical Expression

E = max(0, (A − L + G − X)) × R

Where E = Estate Tax Due, A = Total Assets, L = Total Liabilities/Deductions, G = Lifetime Taxable Gifts, X = Exemption Amount, R = Tax Rate (40%).

Real-Life Example

Scenario: A decedent in 2026 has an estate valued at $25,000,000 in total assets. Outstanding debts and administrative expenses total $3,000,000. There were $2,000,000 in lifetime taxable gifts (over annual exclusions).

Calculations:

  • Net Estate = $25,000,000 − $3,000,000 = $22,000,000
  • Taxable Estate = $22,000,000 + $2,000,000 = $24,000,000
  • 2026 Exemption = $15,000,000
  • Excess over Exemption = $24,000,000 − $15,000,000 = $9,000,000
Estate Tax Due = $9,000,000 × 40% = $3,600,000

The estate would owe approximately $3.6 million in federal estate taxes before any additional state-level taxes or marital deductions (if applicable).

💡 Tip: Proper estate planning — such as gifting strategies, charitable trusts, or marital transfers — can significantly reduce or eliminate estate tax liability.

Frequently Asked Questions

What is the difference between estate tax and inheritance tax? +
Estate tax is paid by the estate itself before assets are distributed to heirs. Inheritance tax is paid by the individual beneficiaries receiving assets. The federal government only imposes an estate tax; inheritance taxes exist only at the state level (if applicable).
Does the marital deduction apply automatically? +
Yes, assets left to a surviving spouse are generally exempt from federal estate tax regardless of amount, thanks to the unlimited marital deduction. This calculator assumes no marital deduction is applied unless specified — for most scenarios without spousal transfer, it provides a baseline estimate.
What happens if my estate exceeds the exemption? +
Only the amount above the exemption is taxed at 40% (federal level). The tax is due nine months after the date of death, though extensions may be available. Proper planning with trusts and gifting can reduce exposure.
How do lifetime gifts affect my estate tax? +
Lifetime taxable gifts (gifts exceeding the annual exclusion of $19,000 per person in 2026) reduce your available unified credit dollar-for-dollar. These gifts are added back to your taxable estate when calculating potential estate tax liability.
Does this calculator include state estate or inheritance taxes? +
This calculator focuses on federal estate tax. However, you can enter estimated state estate taxes in the "State Inheritance or Estate Taxes" field to see their impact on the net taxable estate. State laws vary significantly, so consult local guidance.
